Definitions

  • the present invention relates to a body structure of a vehicle, and particularly relates to a side body structure of a vehicle in a hinge pillar, and a part therearound.
  • a pair of left and right front-side frames provided in a front part of the vehicle extending in vehicle longitudinal directions, crashes and absorbs the impact load, and via the front-side frames, distributes the impact load to various vehicle parts, in order to reduce cabin deformation.
  • a front wheel in the overlapped area may move rearwardly (retreat) with respect to the vehicle body and the impact load may be applied from the front wheel to a hinge pillar extending in a vehicle vertical direction.
  • the applied impact load is distributed rearwardly via structures, such as a side sill extending rearwardly from a lower end of the hinge pillar, a front pillar extending upwardly and rearwardly from an upper end of the hinge pillar, and an impact bar of a front door attached near the hinge pillar.
  • the distribution of the load from the hinge pillar to various parts on the rear side reduces the retreating of the hinge pillar and a dashboard and, as a result, reduces the cabin deformation.
  • the hinge pillar is continuously formed with a closed section space extending vertically between the inner and outer hinge pillar members, and thus, a suitable load transmission occurs between the lower end and the upper end of the hinge pillar.
  • the side sill is continuously formed with a closed section space extending in the vehicle longitudinal directions, and thus, a suitable rearward load transmission via the side sill is achieved.
  • JP2013-159290A discloses a structure in which an inner reinforcing member extending in vehicle longitudinal directions is disposed inside a connecting part between a lower end part of a hinge pillar and a front end part of a side sill to form another closed section space. It is considered that the bucking of the front end part of the side sill is reduced in this structure. According to this structure of JP2013-159290A, an impact load is effectively distributed rearwardly via the side sill extending rearwardly from the lower end part of the hinge pillar.
  • the present invention is made in view of the above issues and aims to provide a side body structure of a vehicle, which effectively distributes a frontal impact load applied to a hinge pillar to a vehicle rear side.
  • a side body structure of a vehicle which includes a hinge pillar extending in vertical directions of the vehicle, a hinge reinforcement disposed in the hinge pillar, and a reinforcing member disposed in the hinge pillar and extending in the vertical directions.
  • the hinge reinforcement is provided with an overlapping section provided on a rear side of a portion of the reinforcing member and overlapping in the vertical directions with the portion when viewed from a vehicle front side.
  • the reinforced part of the hinge pillar when an impact load is applied to a part of the hinge pillar where the reinforcing member is provided in the vertical directions (hereinafter, this part is referred to as “the reinforced part of the hinge pillar”), since the reinforcing member extending in the vertical directions is disposed in the hinge pillar, a rigidity of the hinge pillar is increased by the reinforcing member so that bending of the hinge pillar due to the impact load is reduced.
  • the hinge reinforcement is provided with the overlapping section provided on the rear side of the portion of the reinforcing member and overlapping in the vertical directions with the portion when viewed from the vehicle front side, when the reinforcing member receives a frontal impact load applied to the reinforced part of the hinge pillar, it collapses rearwardly together with the reinforced part due to a moment generated by the impact load. Then, the portion of the reinforcing member is displaced rearwardly in relation to the hinge reinforcement, and contacts with the overlapping section of the hinge reinforcement and a part therearound.
  • the hinge reinforcement functions as the support of the hinge pillar and the reinforcing member, and the hinge pillar is prevented from collapsing further rearwardly.
  • the contact between the reinforcing member and the hinge reinforcement allows the impact load to be transmitted from the hinge pillar to the hinge reinforcement via the reinforcing member, and further rearwardly via a front pillar extending upwardly and rearwardly from an upper end of the hinge pillar, and an impact bar of a front door attached near the hinge pillar.
  • the hinge reinforcement may have a base surface part fixed to the hinge pillar and a side wall part extending inwardly in width directions of the vehicle from the base surface part.

  • the overlapping section may include the edge part.
  • the reinforcing member when the reinforcing member receives the impact load, it collapses rearwardly together with the reinforced part of the hinge pillar, and the portion of the reinforcing member is displaced rearwardly in relation to the hinge reinforcement and contacts with the edge part of the hinge reinforcement and a part therearound.
  • the frontal impact load applied to the reinforced part is transmitted from the hinge pillar to the side wall part or the edge part of the hinge reinforcement and then to the base surface part via the reinforcing member, and further transmitted rearwardly from the base surface part via the front pillar and the impact bar. In this manner, the cabin deformation is reduced while distributing the frontal impact load effectively rearwardly.
  • the side body structure may further include a side sill extending in longitudinal directions of the vehicle and connected to the hinge pillar.
  • the reinforcing member may be partially fixed to the side sill.
  • the frontal impact load applied to the hinge pillar is transmitted rearwardly via the side sill connected to the hinge pillar.
  • part of the impact load applied to the reinforced part of the hinge pillar is transmitted from the hinge pillar to the side sill via the reinforcing member, and further transmitted rearwardly. In this manner, the rearward transmission of the impact load is effectively achieved.

  • the hinge pillar reinforcement 100 is supported by both the front side wall portion 51 a and the front edge portion 51 b of the hinge reinforcement 50 , the function of the hinge reinforcement 50 as the support for the hinge pillar reinforcement 100 collapsing rearwardly is enhanced.
  • the cabin deformation due to the hinge pillar collapsing is reduced while the frontal impact load applied to the hinge pillar is effectively distributed rearwardly by using the reinforcing member capable of reducing the bending of the hinge pillar. Therefore, it is possible to suitably use the present invention in the industrial fields of manufacturing automobiles with hinge pillars.
